What it is about
NGINX Plus ist die kommerzielle Variante von NGINX, einer Webserver-, Reverse Proxy- und E-Mail Proxy Software. NGINX ist eine Webserver-, Reverse Proxy- und E-Mail-Proxy Software. Ein Angreifer kann mehrere Schwachstellen in NGINX Plus und NGINX ausnutzen, um einen Denial of Service Angriff durchzuführen, um Daten zu manipulieren, um Sicherheitsvorkehrungen zu umgehen, und potenziell um beliebigen Programmcode auszuführen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
